The hopper has a 9.16 cu yd (7 cu m) capacity as standard with a drop rear door for use in conjunction with a mobile crusher.

The machine is equipped with three hydraulically folding discharge conveyors allowing for maximum stockpiling capacity and associated benefits of rapid set up and tear down times.
